TL;DR: A free single-variable Calculus course covering limits, derivatives, the chain rule, optimization, related rates, integrals, the Fundamental Theorem of Calculus, areas, and volumes. Self-paced lessons with worked examples and free worksheets for every topic.
Key takeaways:
- Covers single-variable differential and integral calculus.
- Includes limits, derivatives, applications (optimization, related rates), integrals, areas, volumes.
- Each topic has a lesson plus a free worksheet with worked-out solutions.
- Built for high school AP Calc students and first-year college calc students.
- Self-paced and free, no signup.
- Differential Calculus: This area deals with the concept of the derivative, which allows us to understand rates of change. For instance, if you’re looking at how a car accelerates, differential calculus helps you determine the car’s speed at any given moment. It involves understanding slopes of curves and how these slopes change.
- Integral Calculus: This area focuses on the concept of the integral, which is essentially about accumulation. For example, if you know the rate at which a tank is being filled with water, integral calculus lets you figure out how much water is in the tank over time. It involves adding up infinitely many tiny quantities to find the whole.
Both of these concepts rely on the fundamental notion of limits, which is the idea of approaching a value (but not necessarily reaching it). Calculus has vast applications in science, engineering, economics, statistics, and many other fields. It provides a framework for modeling systems in which there is change, and a way to predict and understand the behavior of those systems.

Frequently Asked Questions
What is a calculus course?
A calculus course teaches the math of change. A first course, often called Calculus 1 or single-variable calculus, covers limits, derivatives and their uses, such as optimization and related rates, then integrals and the Fundamental Theorem of Calculus, which links the two. For example, if you know a car’s position over time, the derivative gives its speed at each moment.
Is calculus class hard?
Calculus feels hard to many students, but usually because of shaky algebra and trigonometry rather than the new ideas themselves. If you can factor, work with exponents and logarithms, and use the unit circle comfortably, derivatives and integrals become much more manageable. Steady practice helps most: one lesson and a short worksheet each day beats cramming before a test.
What is the AP Calculus course?
AP Calculus is a College Board course taken in high school that can earn college credit with a qualifying exam score. AP Calculus AB covers limits, derivatives, integrals and their applications. AP Calculus BC includes everything in AB plus topics such as infinite series, parametric and polar functions, and more integration techniques. Credit policies differ by college, so check with the schools you are considering.
What are the calculus courses in order?
At most colleges the sequence is Calculus 1 (limits and derivatives, often ending with basic integrals), Calculus 2 (integration techniques, applications of integrals, sequences and series) and Calculus 3 (multivariable calculus with partial derivatives, multiple integrals and vectors). Differential equations and linear algebra often follow. Before Calculus 1, students usually finish Algebra 2 and Pre-Calculus. Course content varies, so check your school’s catalog.
What is the hardest calculus course?
Many students say Calculus 2 is the hardest, because it combines many integration techniques and introduces infinite series, which feel different from earlier topics. Others find Calculus 3 tougher because it asks you to picture surfaces and vectors in three dimensions. Which one challenges you most depends on your strengths, but solid algebra and trigonometry make every level easier.
Is there a free calculus course?
Yes. The Ultimate Calculus Course on Effortless Math is free and self-paced. It covers single-variable calculus from limits through derivatives, the chain rule, optimization, related rates, integrals, areas and volumes. Each topic has a lesson with worked examples and a free worksheet with worked-out solutions, which suits high school AP Calculus students and first-year college students.
